Purpose
Diagnostic procedures for well pump issues — addressing a gap in existing Spartan SOPs.
When to Use
- Customer on well water reports no water, low pressure, intermittent water, or pump running constantly
- Pump sounds like inhaling air, or water is discolored/sandy
Diagnostics
No Water or Low Pressure
Check pressure switch — is it calling for pump? Check cut-in/cut-out pressures
Check pressure tank — tire gauge on Schrader valve (should be 2 PSI below cut-in)
Listen at wellhead — pump running? Humming? Silent?
Check electrical: breaker, wiring to switch, wiring to pump
If running but no delivery, pump may have lost prime or failedPump Runs Constantly
Check for leaks (running toilet, supply line leak)
Check pressure tank for waterlogged condition
Test pressure switch operation
No leaks and tank is good: pump may be failing or well level droppedPump Sounds Like Inhaling Air
Water table may have dropped below pump intake depth
Check well depth and static water level if records available
Pump may need to be lowered deeper
Specialized job — ensure you have well puller, wire, pitless adapter, torque arrestorDiscolored or Sandy Water
Check well screen/filter for damage
Sand indicates failing well screen or pump set too deep
Iron/rust: common in Ohio wells — recommend water treatment
Perform water quality testing: hardness, pH, iron, contaminantsPressure Tank
Pre-charge with tire gauge on empty tank — should be 2 PSI below cut-in
Waterlogged tank causes rapid cycling — recommend replacement
Check for corrosion at tank fittingsImportant Notes
- Well pump diagnostics can be complex — call supervisor if unsure
- Well pump pulling requires specialized equipment — coordinate with dispatch
- Always test water quality on well calls — opens door for treatment upsells
- Ohio does not require well drilling license for pump service
